Abstract
The utility model discloses a ventilative valve, its characterized in that: this ventilative valve is equipped with a U shaped steel pipe (1), and a straight tube (2) is extended to the one end of U shaped steel pipe (1), and the tip of straight tube (2) is equipped with the inscription silk, and just the external silk with air silk head (3) one end closes mutually soon, the other end of air silk head (3) is equipped with the external silk of air silk head (4). The utility model discloses can solve that high -pressure gas communicates with each other and exchanges with the atmosphere in the box, can prevent debris getting into the such as granule in the external atmosphere, cooling water simultaneously to this device simple structure, convenient operation.
Description
Technical field
The utility model belongs to mechanical device technical field, particularly relates to a kind of vent valve of mechanical device.
Background technique
The a lot of rotary part of mechanical field, designing requirement uses thin oil circulating lubrication, equipment requirement could be met, rotary part thin oil rotary lubrication is usually in containment housing, due to rotary part High Rotation Speed, usually to cause in casing that gas temperature raises, pressure increase, as can not in time and the external world carry out gas exchanges, usually cause some equipment failures.And now use ventilation valve structure complicated, using effect is desirable.
Summary of the invention
The utility model now uses ventilation valve structure complicated to overcome at present, and the problem that using effect is desirable, the utility model provides a kind of novel ventilated valve.The technical solution of the utility model is as follows: a kind of vent valve, is characterized in that: this vent valve is provided with a U-shaped steel pipe, and one end of U-shaped steel pipe extends a straight tube, connects silk, and screw mutually with the external silk of the first end of air silk in the end of straight tube is provided with; The other end of air silk head is provided with the external silk of air silk head, with on casing in connect silk and screw.Working procedure of the present utility model is that U-shaped permeability cell and the first end of air silk are screwed, and then spins together with needing the casing installing vent valve, realizes casing inner high voltage gas and communicates with barometric pressure and exchange.
The utility model can solve casing inner high voltage gas and communicates with air and exchange, and can prevent the foreign material such as particle, cooling water in ambient atmosphere from entering casing, and this apparatus structure is simple, easy to operate simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein, 1, U-shaped steel pipe, 2, straight tube, 3, air silk head, 4, the external silk of air silk head.
Embodiment
Below in conjunction with embodiment, the utility model is described further; A kind of vent valve, it is characterized in that: this vent valve is provided with a U-shaped steel pipe 1, one end of U-shaped steel pipe 1 extends a straight tube 2, connects silk, and screw mutually with the external silk of air silk head 3 one end in the end of straight tube 2 is provided with; The other end of air silk head 3 is provided with the external silk 4 of air silk head.
During use, screw connecing silk on external for air silk head silk 4 and casing; Realize casing inner high voltage gas communicate with barometric pressure and exchange.
